Your wife is going to love this; Pre heat your oven to 450 degrees and cook the rods for 8 hours. That's it.
First heard of this in 1969--it started with having to heat treat the rear end gears in a Chevy 12 bolt. Doing the heat treating allowed the gears to last a whole season instead of 4 or 5 runs.
Same idea with rods---it works.
BTW; Some guys think 16 hours is better-- not sure I agree.
BTW2: do you want me to look over the heads and see what porting you can do? The "old" Sportmans had a very bad exhaust port.
